QuestionQUESTION: Where exactly is the TCM located? I am getting code 700 and 605 and had the
tranny rebuilt about 6 months ago. I'd like to change it myself
ANSWER: a 605 is internal PCM failure not TCM and the p700 just is giving a code for the tranny computer to which U will need a better scanner to get those. If u have a gray key U cant replace the computer with out a dealer scanner and also U will need a dealer to program the PCM once installed.
sorry 605 is internal TCM P0605-INTERNAL TCM .
